Boehner is pursuing a lawsuit against Obama, charging that the president “has not faithfully executed the laws” on a wide range of issues, including health care. The speaker said in an op-ed column for CNN that the GOP-controlled House will bring legislation to the floor this month authorizing such a lawsuit.

Palin said in Breitbart News that Obama’s response to an influx of immigrants crossing the U.S.-Mexico border illegally “is the last straw” and called for the president’s impeachment.

Palin, the 2008 GOP vice presidential nominee, said in an interview with Sean Hannity on Fox News that a message needs to be sent to Obama that he is “not an imperial president.” She sounded dismissive of Congress, saying “Washington is broken,” and of Boehner’s lawsuit.

“You don’t bring a lawsuit to a gunfight, and there’s no room for lawyers on our front lines,” Palin said.
